1' c all whrm't it: may concern.-

Be it known-that l', WiLLIAM R. MAR-EN?- 'JE'ITE, asubject of the Kingof'Great- Britain, residing at Detroit, inthe county of Wayne and Stateof Michigan, have invented' eertain new and useful Improvements in Vehicle- Heaters, of which thefollowing'is a specification, referencebeing had thereinto the accompanying drawings.

. This invention relates to improvements in licaterslor vehicles,.a1'1dmore especially to lu-aters for closed. earriagessuch' as hacks,omnibuses, &c. -the-objectofthe same being to provide aneilicienti'oilor vapor burning heater which is. soconstructeda that none of theFunnies, gases, or smokeefron the oil or burner can in-any way get intothe carriage and so as to adapt the heater to be readily attached to thecarriage where none'of: the useful inside space-will be taken up therebyand where the heated air-will pass directly into thevehicle inthe mostellective manner.

it isalsoanobject ofthe invention to so construct the heater that thepure outside air will be drawn in, heated, andpassedinto the" carriage,thus drivingout the foulair therein and creating a circulation and toarran e the device so that. all-0t its parts are readi y accessible-andsothat it may be accurately regulated from the inside of the vehicle.

A further object of theinventi'on-is to rovidc acheapand.simpleconstruction w ich may be'readily cleaned-or repaired'andwhich is provided with certain other new and useful features and has theseveral advantages of the particularconstruetion, arrangement, andcombination of parts, all as hereinafter'more fully described, referencebeing had to the accompanying drawi n s, in which Figure 1 is a side eevation of a carriage with parts broken away to show the heater inoperative position; Fig. 2, a partial side elevation of a carriage withparts broken away and showing a modified arrangement of the supply-tank.Fig. 3 is a perspective view of the heater; Fig. 4, a longitudinalvertical section of the same; Fig. 5, a transverse section of theheater. Fig. 6 is a perspective view of a modified form of heater, andFig.7 a vertical section through the same.

As shown in the drawings, A is the bottom or floor of the carriage-bodybetween the opposed seats B, an 0 )ening A being provided in said floor,and a eater (l is secured to the under side oi said bottom opposite theopening.

' D is the drivers seat at the frontof the vehicle, beneath which theoil-supply tank E- may be placed, and a supply-pipe F extendsfrom saidtank downwardthrough the body I beneath theforward seat-and out tln'oughthe bottom to the heater, a regulating-valve G I withasuflicient spacebeneath the rear seat 'B asshown in Fig. 2,.or beneath. either olsaidscats, thetank may be placed in this space and connected with theheater by the supply-pipe, as shown, or said tank may be locatedin anyother suitable space in the vehicle, according to the construction ofthe body. I

The heater (1 consists oi" a suitable rectangular' casing 1',-providedwith aperturcd ears 2, projecting from its sides at the upper edgesthereof, by nieansot' which said casing is secured by bolts to the underside of the carriage-fioor with its door or hinged cover 3 upposite theopeningA in the iloor. The casing outside air is admitted to thecasingthrough holes 4 in its ends, where it is heated and dischargedthrough openings or slits 5 in the cover 3, which slits are controlledby-a slide (5;

ward through the cover where the occupants of the carriage may readilmove the same to open or close the slits and regulate the admission ofthe heated air to the carriage.

Supported within the casing 1 in any suitable manner is a cylindricalradiator 8, made in halves hinged together at one side, said halvesbeing each jecting hollow protuberances 9 to increase theradiating-surface, and supported within the longitudinal axis of theforated burner-tube 10, which extends at one end through an openingint-he end of the. radiator and is provided with a funnel-shaped tance anozzle or contracted point 12 on the end of the oil-supply pipe, saidpipe being extended through an opening in the end of the casing andsecured therein. Extending through an opening in the opposite end ofsaid casing and also through an opening in the adjacent end of .the.radiator is a discharge Where the carriage-body is constructed is thushung beneath the vehicle-body and operated by a lug or handle 7,projecting upformed with radiallypro radiator is a pcrend 11, into whichprojects for a short dis-- or exhaust pipelS, through which the odorsand. products of combustion esca e into the open air beneath thevehicle, an a pipe 14, extending through the bottom of the radiator andeasing, supplies air to the radiator to maintain combustion therein.

The oil issues from the nozzle 12 in a fine spray and entering theburner-tube draws in through the funnel a sufiicient quantity of air tomix therewith and form a combustible vapor, which passes through thefine jet openings in the tube and burns in small jets within the closedradiator, the halves of which fittogether tightly enough to prevent anygases or products of combustion from escaping into the casing andpassing therefrom into the carriage. The burner may be readily lightedor the interior cleaned or repaired from the I inside of the carriage byraising the cover 3 and the hinged upper half of the radiator.

In Figs. 6 and 7 is shown a modified form of heater, the differencebeing principally in the shape and size of the same rather'than in theconstruction, the casing 15 being cylindrical or circular in form andprovided with ears 16 at one end for its attachment to the floor of thevehicle. A circular cover 17 fits the upper open end of the casing, anda discous slide or damper 18 is provided to close the openings therein.Air-intake openings 19 are provided in the lower end of the casing, anda radiator 20 of a shape to correspond to the shape of the easin issupported therein by pipes 21, opening t irough the bottom of theradiator and also through the casing, which pipes also serve to supplyair to the radiator to maintain combustion therein. The

' radiator is formed with hollow 1protuberances the radiator, and afunnel-shaped end 25 on said tube extends through the bottom of theradiator to receive the spray-nozzle 26 on the end of the supply-pipe,which extends upward through the bottom of the casing.

On certain styles and sizes of vehicles it may be found desirable to usethe modified form of burner; but as its operation is sub stantially thesame as that of the first described burner I do not wish to confinemyself to this or any other particular form or configuration.

Having thus fully described my invention, what I claim is 1. In avehicle-heater, the combination of a casing provided with openings forthe admission of air and having an open top, laterally-projecting earson the sides of the casing at their upper edges by means of which thecasing is attached to the bottom of a vehiclebody, a cover hinged to thecasing to close the top thereof and provided with openings for theescape of the heated air, a slide carried by said cover to close the oenings, a cylindrieal radiator provided witii hollow protuberances onits surface supported within the casing and provided with an upperportion hinged to the lower portion, pipes extendin through the casingand communicating with the interior of the radiator to supply airthereto to maintain combustion therein and to draw off the products ofcombustion, a perforated burner-tube supported in the axis of theradiator with one end extending through the end of said radiator, afunnel on the end of the burner-tube outside the radiator, an oil-supplypipe extending through the casing, and a nozzle on the end of thesupply-pipe extending into said funnel, and an exhaust-pipein theopposite end of the casing and supporting the end of the radiator, oneend 0 said tube being supported by said funnel, and means for sup ortingsaid tube at the other end from within the radiator.

2. In a vehicle-heater, a casing having integral securing-ears andopenings for the'admission of air, a hinged cover with openings, and amovable plate cooperating therewith, a perforated burner-tube extendinglengthwise of said casing, .a cylindrical radiator inclosing said tube,said tube being support- 1 ed from within said radiator and outofcontact with the walls thereof, means for suplying air to said radiator,an exhaust-pipe rom said radiator, and a fuel-supply to said WILLIAM R.MARENTETTE.
